AI Caption Generator
Generate on-brand captions with hooks, CTAs and hashtags tuned to each platform’s algorithm.
Everything you need for social media
Powerful features to automate your entire social media.
Per-Platform Caption Adaptation
Captions are automatically reformatted for each platform — concise for X, professional for LinkedIn, conversational for Instagram.
Brand Voice
Describe your tone, your audience and your editorial rules once — every caption is written from them.
Hashtags Proposed for You
Each caption comes with a mix of broad, mid-range and niche hashtags that you can keep or cut.
Hook & CTA Generator
Generate attention-grabbing opening lines and clear calls-to-action that drive clicks, saves, and comments.
Emoji & Formatting
Smart emoji insertion and line-break formatting tailored to each platform's best practices for readability.
Multilingual Captions
Captions are written in the language of each brand’s audience — English, French, Spanish, German and others.
How it works
Get started in 3 simple steps.
Describe Your Brand
Set your business, your audience and your tone once. Pulpi can pre-fill them from your website.
Connect Your Networks
Each connected network gets its own version of the caption.
Generate, Edit & Schedule
Review AI-generated captions, make any edits, then schedule directly to your content calendar.
Who uses it, and for what
The photo is usually the easy part. What stops a post from being published is the twenty minutes spent staring at an empty caption field, and that friction is what turns a daily habit into a monthly one.
The visual creator
The problem. You shoot constantly and post rarely, because the caption is the tax on publishing and you keep deferring it.
With Pulpi. Captions arrive with the image, in your register. Publishing stops being a writing task and becomes a choosing task.
The brand with a strict tone
The problem. Captions are written by several people and the voice wanders, which is exactly what a brand guideline was supposed to prevent.
With Pulpi. One voice profile applies to every caption regardless of who is on shift. Guidelines stop being a document nobody opens and become the default output.
The account posting across platforms
The problem. The same caption goes everywhere, which means it is slightly wrong everywhere: too long for X, too flat for Instagram, too casual for LinkedIn.
With Pulpi. One idea, adapted per platform in length and register, without writing it four times.
What people ask before switching
Will the captions sound like everyone else’s?
Generic prompting produces generic captions, which is the sludge you see everywhere. Pulpi writes from your profile, your audience and your offer instead of from a template, and the difference is visible. You edit anything that still misses.
Does it add hashtags automatically?
It proposes them, mixing broad and niche tags for the platform in question, and you keep or cut them. Hashtag strategy differs enough between Instagram, TikTok and LinkedIn that a single set would be wrong on at least two.
Can it write in my language?
Yes, natively rather than by translating English. A translated caption reads as translated, which is worse than a plainer caption written directly in the target language.

Frequently Asked Questions
Does the AI caption generator work for all social platforms?
Yes. Pulpi.ai writes a caption for each of Instagram, Facebook, X, LinkedIn, Pinterest, YouTube, TikTok, adapted to the style and character limits of the network.
How does brand voice training work?
During setup you describe your brand — tone, audience, sector — and add editorial rules. Every caption is written from that profile.
Can the AI generate captions in multiple languages?
Yes. The language is set per brand, and every caption for that brand is written in it. A business with two regional audiences uses two brands.
Can I use the caption generator without scheduling?
Absolutely. Copy captions directly for use anywhere — your website, email newsletter, or manual posting. You're not required to schedule through Pulpi.ai.
Can it write captions for images I upload?
Yes. Upload a photo or a video for a brand: Pulpi writes the caption in the voice of that brand, or publishes yours exactly as written if you prefer.
How long should a caption be?
It varies by platform and the generator adapts: short and punchy for TikTok, room for a story on Instagram, more structure on LinkedIn.
